Snap fastener



, citizen ofthe United States, residing at the city of St. Louis, State'of Missouri, have patented Dec. i9, 1F22, v l

`Pani. s. iones, `or sr. Louis, "riissoner Y Application .filedSeptember 12, 1921.' Serial No. 499,908.`

To all whomkz' may concern: v

Beit lrnownthat I, PAUL t. JoNEs, `a

invented a certain new and useful Improve.- inent in Snap Fasteners, ofwhich the following is a specification, reference being had l to theaccompanying drawing, forming` a part thereof.

rilhis invention relates generally. to snap fasteners'. and, moreparticularly.. to :snap fasteners of the type comprising separableelements for use on wearing apparel. The principal object of my' presentinvention is to provide a Vfastener of the type stated of simple,durable, and inexpensive construction comprising readily separableelements which, when united, are substantially incapable ofrelative'movement, to the end that the apparel parts to which theelements are attached are relatively immovably fixed. l v

A further object of `iny invention is to provide a snap fastenei'element rhaving a snap seat formed by rolling or drawing an integralpart of the element7 thereby forining a relatively inexpensive seatorreceiv- :ing part for the spring-retainer cf the companion element,and which pari` byr its 'formation is relatively7 rigid and less liableto distortion than those of the art ofy whichl amaware.

it still further object of my invention is to generally iniprove'upoiiand-'simplify the 'construction o snap-fasteners of the kind described.V n

With'the above and other objects .in view, my present invention residesinthe novel features of form, construction, arrangement, and combinationof parts hereinafter described and afterwards'pointed out inthe claim.

' vin the accompanying drawing, n

two (Jo-operating and complementing ele-- ments er 'members' kbeingshown yas' united and relativelylocked. AReferring now more in detail tothe-drawmg, which illustrates ay practical embodiinent-y ofk myinvention,` and in vwhich ylike reference 'characters'y refer to ililieparts throughout the lseveral views, `l-designates` the seat or lockedelement lof the fastener and 2! the spring or plockingelement, eachy ofwhich comprisesl a body formedof a single piece of suitable material andpreferably formed las a `dislr of sheet metal'.

By preference, the elements` or members land 2 eachcomprise'substantially flat -or plane bodies 3 and t, respectively,surrounded by rims 5 and 6, respectively, which rims, i

when the members land 2 are juxtaposed, are relatively spaced toforni agap 7, whereby the separation of the elements is *facilitated by wedgingaction of the fingers orthe The seat or locked a roll or `head 8preferably intheform of an open endedv cylinder constructedyintegrally'out of the body of the element as by element l comprises,

formingparallel incisions from its margin-f Vand rolling or drawing theintermediate -material between such iificision'sandl of which cylinderthe bowed or lenticular sides .9 are the essentialsand which providethek lock-receiving seats l0, 1l,y which are relatively divergentupwardly or away from the plaine of the body toa point within the heightofy the roll and then relatively con-k i'eigent toward the top of theroll.

The element is provided with upstanib" ing vflanges 12 preferablystruck' from Vthe plane body il, and between which is formed asubstantially rectangular opening or aperture 13 shaped to admit theinsertion of the vroll or head S. of the elementi therethrough andpreferably of dimensions to snugly lit the rollv or head 8 to preventrelative movement of the elements l and 2 when detachably united. y

rEhe lock proper consists of a substantially U-shaped spring constructedof a. single sec-` tion of wire and whose legs 14 andl laie disposedalong opposite margins of the opening 13 and held relatively spaced by.the

upstanding flanges .1Q and `against movement lengthwise by being securedin the rim 6 as by having 'the rim ,crimped 'thereover, as

shown. The lock is preferably madel and secured as shown in Figure 2,and its essential is a yieldingly mounted han such as the leg 14, Whosenormal or locking position is Within the plane of the opening` 13,Wherehy said bar or legwill normally, as when inv lockingposition, beagainst the seat 10 of the roll or head 8 of the element l, ras shown inAFigure. 5, the locking engagement between the 1oar l0 and roll or head8 being suppleniented by the yielding tension of the other e leo or barl5 oifthe spring.

isiy new snap fastener may be conveniently and inexpensivelymanufactured, may Le readily attached tor the i\feaiiiigappaiei,threadppenings 16 being` provided 'in ythe elements for the purpose, andis-exceedingly ei'icient inuse and operation.

l am aware that changes in the iorrn, construction, arrangement, and`combination of the several parts of yrnyiiew snap fastener may .be madeand substituted 'for those here` in shown andpdescrihed Withoutdeparting from the nature and principle of my invention, f

Having thus described my invention, what l claim and desire to secure byLetters Patent is: y

A snap-fastener comprising a member including an approximately lat.disk-shaped body-portion provided with an approximately rectangularaperture, a substantially U-shaped spring having engagement at its hightand at one oi? its ends With said bodyportion, the legs of the springbeing disposed upon opposite sides and normally approximately in theplane ot said aperture, and upstanding anges disposed on saidbody-portion upon opposite sides of the aperture and having engagen'ientwithtlie legs oi `the spring Jroi' maintaining Vthe saine in spacedrelation, in combinationwith a see vond *complementing nieinloer`including` a similar approximately ila-t disk-shaped bodyfportionprovided integrally with a cylindrical head shaped up therefrom andadapted for projection lthrough the aperture ci the rfirst membery andfor locking engage ment with said spring. e i

ln testimony whereof, I have signed my name to this specification.

PAUL s. Josse.
